摘要： An electric storage battery and method of manufacture thereof characterized by a feedthrough pin which is internally directly physically and electrically connected to an inner end of a positive electrode substrate. A C-shaped mandrel extends around the pin and substrate end enabling the pin/mandrel to be used during the manufacturing process as an arbor to facilitate winding layers of a spiral jellyroll electrode assembly. The pin additionally extends from the battery case and in the final product constitutes one of the battery terminals with the battery case comprising the other terminal. Active material is removed from both sides of the outer end of the negative electrode in the jellyroll to allow room for adhesive tape to secure the jellyroll. The electrolyte is injected through the open end of the case after the endcap is welded to the negative electrode but before sealing the endcap to the case. The electrolyte is preferably injected through the C-shaped mandrel to facilitate and speed filling.

摘要： A process for assembling an electrochemical cell that utilizes an electrode containment shield to prevent internal electrical short circuits that are caused by fragments of a frangible electrode coming into contact with the battery's opposing electrode. The shield, which may be secured to the current collector, is particularly useful with low volume seals that do not support the separator.

摘要： An end cap assembly is disclosed for sealing the open end of a cylindrical alkaline cell housing preferably having a diameter less than the diameter of AAA size cells. The end cap assembly is preferably intended for sealing AAAA (LR61) size cylindrical alkaline cells. The end cap assembly comprises a terminal end cap, an insulating sealing disk underlying said end cap, and an elongated current collector penetrating through an aperture in said insulating sealing disk. At least a portion of the insulating sealing disk lies within the cell housing to seal the open end thereof. The terminal end cap has a peripheral edge, preferably formed from a curved rib, which is locked within the peripheral edge of the insulating sealing disk. The end cap assembly does not require other metal disks held within the sealing and insulating disk. The insulating disk comprises a discontinuous skirt comprising a plurality of integral legs emanating downwardly into the cell interior from the peripheral edge of said insulating disk. The insulating sealing disk has an integrally formed rupturable membrane therein. The membrane ruptures when gas pressure within the cell exceeds a predetermined level.

摘要： An electrochemical cell has a wheel shaped, molded plastic seal member of a unitary construction which includes a central cylindrical hub from which depend in outward radial sequence, an annular pressure vent, a boss, a downward projecting skirt, an annular flexure means for providing radial movement and an outer rim terminating at its periphery in a cylindrical wall. The pressure vent includes a thin membrane ring depending from the hub which joins the hub to an annular diaphragm. A hinge ring joins the periphery of the diaphragm to the boss. The seal member is designed so that the membrane ring fails primarily in shear at excessive cell pressure which makes the vent more reliable and easier to fabricate.

摘要： This invention relates to a seal for a cylindrical alkaline cell. The member includes a metal support having an annular spring disposed at the outer periphery. The spring is placed under compression by a radial crimp and the spring is adapted to expand and contract whereby the seal is maintained during thermal cycling. The member also includes a plastic grommet having an annular vent designed to open at very high pressures whereby said seal member is particularly useful in alkaline cells having little or no mercury whereby high internal pressures can develop.

摘要： A cover for a galvanic cell having a reverse curved peripheral edge and a substantially centrally disposed upstanding wall bounding an aperture. A sealing member is positioned below the cover and has a tubular hub which projects through the aperture in the cover and a skirt that electrically insulates the edge of the cover. An electrically conductive fastener is positioned in the tubular hub on the sealing member which tends to cause the edge of the tubular hub to roll or "mushroom" when the electrically conductive fastener is peened or clinched in place. The rolled tubular hub tightly locks the fastener and the cover together while the edge of the cover presses against the inner wall of the container holding the components of the galvanic cell. The pressure tends to slightly bow the cover enabling it to stay in a tightly sealed condition under both physical and thermal stress. A galvanic cell incorporating the cover is also disclosed.
